Optimize Your Laptop’s Cooling with an Original Asus Heatsink

Essential Cooling for CPU and GPU Performance

The Asus laptop heatsink plays a crucial role in maintaining optimal operating temperatures. It connects directly to the CPU and GPU, transferring heat via copper heatpipes to the cooling fins where it's expelled by the fan. If your system overheats, throttles performance, or shuts down unexpectedly, a worn or damaged heatsink could be the root cause.
Heatsinks often develop issues like cracked heatpipes, clogged fins, dried thermal paste, or warped contact surfaces. Replacing the heatsink restores proper heat transfer, especially when the original module has degraded or been damaged during a previous cleaning.

Benefits of Replacing a Faulty Heatsink

1. Prevents CPU/GPU overheating and throttling
2. Restores thermal balance for stable system use
3.

OEM alignment for proper contact pressure
4. Supports full performance under load
5. Avoids costly motherboard or CPU damage
6. Enhances overall fan efficiency
7. Ensures safe system temperature range
8. DIY-friendly repair with clear installation steps
This part addresses issues like thermal shutdowns, heatpipe leaks, hot chassis surfaces, and poor thermal paste spread. Common search queries include "replace Asus heatpipe assembly" and "fix overheating after cleaning thermal paste".

FAQ – Get Answers Before Replacing Your Heatsink

Is this heatsink model-specific?
Yes. Always check your exact Asus model to match the heatpipe layout and mounting points.
Does it include thermal paste?
No. You must apply fresh, high-quality thermal compound during installation.
Will this stop overheating issues?
Absolutely. Replacing a degraded heatsink restores efficient cooling and reduces heat buildup.
Can I install it myself?
Yes. With grounding, patience, and basic tools, DIY installation is manageable for most users.
How do I test thermal performance?
Use software like HWMonitor to check CPU and GPU temps after replacement.

Why does my laptop get hot during basic use?
Your heatsink may have clogged fins, poor contact, or failed paste. Replacing it solves this.
Do I need to replace the fan too?
Only if it’s noisy or not spinning. Many Asus fans and heatsinks are separate components.
Will thermal paste alone solve the issue?
Sometimes, but a warped or cracked heatsink can’t be fixed with paste alone.
